in reply to Re^3: Executing a string as a Perl command
in thread Executing a string as a Perl command
Depends. If the variable contains a short string, then the slow down will be negligible. If it contains a number and the subroutine needs to do some more computations, then you've just forced perl to convert the number to a string and back. If nothing more, it's wasteful.
Then there is yet another case. What if the variable contains a huge string? You've just made yet another copy ...
